Lynn had an equal number of papayas and kiwis at first. She sold one-quarter of the kiwis and bought another 85 papayas. In the end, she had thrice as many papayas as kiwis. Find the number of kiwis she had at first.

Kiwis |
Papayas |
| Before |
4 u |
9 u - 85 |
| Change |
- 1 u |
+ 85 |
| After |
3 u |
9 u |
The number of papayas and kiwis at first is the same.
9 u - 85 = 4 u
9 u - 4 u = 85
5 u = 85
1 u = 85 ÷ 5 = 17
Number of kiwis that she had at first
= 4 u
= 4 x 17
= 68
Answer(s): 68
